I know it's been holidays and everyone (including me) has been on
vacation, but just wanted to make sure the current status of this
series was explicitly called out.  :-)


I believe patches #1 and #2 are ready to land and will go through your tree.

Patches #3 and #4 should probably go through Andy's tree and are not
urgent (they are just cleanup).  They can sit on the back burner until
patches #1 and #2 have hit mainline.  That's a good reason to land #1
and #2 sooner.  ;-)

I think patch #5 is also ready to land.  There's been some
bikeshedding about the exact format for the opp table, but none of
that bikeshedding affects the bindings that Jordan wrote.  If you
agree that this is OK to land, it would also be nice to get in.

...then Jordan can spin patch #6 (once Rob H Acks Rajendra's opp
bindings) alone at a future date.
